Flooding limitation for multicast

This test checks that the flooding limitation for multicast is working correctly in the network. To protect the network from loops in customer equipment and from malicious DoS attacks, a limit should be imposed on the rate of multicast traffic from an individual customer port. Such a limit needs to be enforced before the traffic reaches the ISP.

Impact: DoS

Test process

Malicious sends IP multicast traffic at a rate twice as high as the multicast flooding limit expected to be in place.

Fail criteria

The rate of the received traffic at the ISP is above the expected limit.
